What is the angle between

(\overrightarrow{\mathrm{P}}+\overrightarrow{\mathrm{Q}})

and

(\overrightarrow{\mathrm{P}} \times \overline{\mathrm{Q}})

View answer and explanation

Correct option: C

\frac{\pi}{2}

Option C (

\frac{\pi}{2}

) is correct because the cross product of two vectors is always perpendicular to the plane containing the two vectors, and the sum of two vectors lies in the same plane.
